Anti-government protesters of the "14 Hundred Self-Defence" group, an Independence Square self-defence unit, hold up their flag as they march around the Ukrainian Parliament in Kiev on February 6, 2014. Ukraine's unrest erupted in November 2013 after President Viktor Yanukovych rejected an association agreement with the European Union in favour of closer ties with Moscow, and the turmoil has now become an all-out movement to oust him. The European Union's foreign policy chief on February 5 offered a downbeat assessment of the crisis in Ukraine after talks with the president while Russia warned Kiev it would only release bailout money if stuck to its old policies.AFP PHOTO / ARIS MESSINISARIS MESSINIS/AFP/Getty Images less
